I uninstalled Unix subsystem, iPogo, Johntool and SummerBoard and everything that is on the screen is the Apple logo, all the time. I've tried to force it into restore mode, but it doesn't work. It won't turn off only by the sleep/wake button, but it turns off with both sleep/wake and home button. When I connect it to the computer and turn it on, it starts synchronizing after 20 sec as normal, but still there is only the Apple logo. EDIT: Ah, forgot that since it syncs with it can be restored from iTunes too. iPod fixed, no problems, no worries.
